SOAPUI Api and Basic auth

Im trying to follow the instructions here:  http://www.soapui.org/architecture/inte ... html  however am stuck when a wsdl/endpoint is behind basic auth.  I am setting username / password on the request, but it looks I need to set somewhere else as well.  Setting on the url causes the first NPE below.  The second NPE looks like its failing to launch the dialog to prompt me username/password.  So that may be a red herring.  Can anyone suggest on how to proceed?

Here is the code I am using to build my request:

        String requestData = soapBeginning + getInputDocument() + soapEnd;
        project = new WsdlProject();
 
              WsdlInterface iface = project.importWsdl(location + getServiceName()
              + "?wsdl", true)[0];
        WsdlOperation operation = (WsdlOperation) iface
              .getOperationByName(getOperation());
        request = operation.addNewRequest("My request");
        request.setUsername(getUsername());
        request.setPassword(getPassword());
        request.setRequestContent(requestData);


If the location of the wsdl i pass in looks like http://username:password@some.host:8080 ... wsdl  I receive a NPE

If i exclude the username/password on the url I get another NPE:
